LongSAGE analysis in skeletal muscle at three prenatal stages in lean and obese pig breeds

ABSTRACT: Obese and lean pig breeds showed obvious phenotypic variations and physiological differences in skeletal muscle growth. Prenatal muscle development programs postnatal performance. In this study we initially conducted full transcriptional profiling of prenatal skeletal muscle from Tongcheng pigs (obese) and Landrace pigs (lean) at 33, 65 and 90 days post coitus (dpc), using long serial analysis of gene expression (LongSAGE). We subsequently sequenced 317,115 LongSAGE tags and identified 1400 and 1201 differentially expressed transcripts that showed eight expression patterns for Tongcheng and Landrace, respectively. These two breeds had more significant differences in their gene expression profiles at 65 than that at 33 and 90 dpc. We also identified 532, 653 and 459 transcripts that were
